expiry is lost during restarts

[dustin]

There are no timestamps shown here, but I did this interactively with a few seconds between interactions. I've got mosquitto running with the following bits of config:

autosave_interval 1
autosave_on_changes true
persistence_file mosquitto.db
persistence_location /tmp/

I run the following command:

mosquitto_pub -r -D publish message-expiry-interval 10 -t tmp/x -m hi1

While that's running, I restart mosquitto a couple times at a few seconds of interval. The following happens:

tmp/x → hi1
  MessageExpiryInterval 10
ERROR: MQTTException "disconnected"
tmp/x → hi1
  MessageExpiryInterval 4
ERROR: MQTTException "disconnected"
tmp/x → hi1
ERROR: MQTTException "disconnected"
tmp/x → hi1

Notice the expiry is gone and the message is permanently persistent. A few minutes later:

mqtt-watch tmp/#
tmp/x → hi1

Possibly related, also interesting:

dsal-macbookpro:mqtt dsal$ mqtt-watch tmp/#

[no message]

I restarted the client a few times. Around the time it should expire, it sent me the message with no properties. After that, the message was gone.
